With two alliance down, and the modly flavour so far, I'm going to conjecture that this game might be loosely based on Bushwhacked
. What worries me about that idea (actually, what inspired that idea) is the possibility of recruiting reavers. I certainly think there's at least one Alliance member left, possibly Commander Harken, but with two of them dead, reavers have to be a higher priority, I'd think. Would we be told if the last member of a faction (in this case, Alliance) was eliminated?
With a confirmed Alliance faction (rather than merely individual alliance indeps), they would have two possible win conditions - either they're standard mafia, or they're after Simon & River. A win condition as narrow as finding/killing two players sounds somewhat unlikely for a larger faction; if there is another Alliance member or two they're likely a full-blown mafia team.
Following from that, if Alliance are standard mafia (and this is getting kinda convoluted, I'll grant), then reavers probably have some kind of twist. Given the lack of reaver-kill - I agree gunfire is not likely to come from reavers - a recruit ability is the most worrying one at this juncture. Counterbalance to that, I suppose, would be that a recruit might be expected to include some kind of flavour indication, and there was nothing of the sort.
Of course, it could be (as Azrael suggests) that the scum all tried to kill the same player (either Amy or Chandani, I would assume), and their kills were all blocked. It could also be that reavers have a daykill, rather than acting at night.
At least having the Operative in the game makes it less likely we have the hands-of-blue guys or Jubal Early, in my opinion.
Final note - I did get a minor ping off Azrael's last 'Amy's amazing, she should be kept alive forever and I sure hope we have town power roles' post, but I'm prepared to disregard it because I largely agree with the sentiment.
